Sofia Turner, a.k.a. Darth Nix, is a Human female Sith Lord from Korribanos. Like many Korribanosian Sith Lords, she sports traditional facial tattoos. She is known to be a supporter of Emperor Raxus Walker, though whether because of personal conviction or loyalty to another Korribanosian is unknown. Incidentally, as her great-aunt was his grandmother, she is the Emperor's second cousin once-removed.

Darth Nix has shown to exert skilled control over fire, often conjuring it from thin air through the Force to distract or even destroy her enemies.
